"Seeing'' Electric Network Frequency from Events
Lexuan Xu, Guang Hua, Haijian Zhang +2
Most of the artificial lights fluctuate in response to the grid's alternating current and exhibit subtle variations in terms of both intensity and spectrum, providing the potential…
Towards End-to-End Synthetic Speech Detection
Guang Hua, Andrew Beng Jin Teoh, Haijian Zhang
The constant Q transform (CQT) has been shown to be one of the most effective speech signal pre-transforms to facilitate synthetic speech detection, followed by either hand-crafted…
Robust ENF Estimation Based on Harmonic Enhancement and Maximum Weight Clique
Guang Hua, Han Liao, Haijian Zhang +2
We present a framework for robust electric network frequency (ENF) extraction from real-world audio recordings, featuring multi-tone ENF harmonic enhancement and graph-based optima…
Reliability of Power System Frequency on Times-Stamping Digital Recordings
Guang Hua, Qingyi Wang, Dengpan Ye +1
Power system frequency could be captured by digital recordings and extracted to compare with a reference database for forensic time-stamp verification. It is known as the electric…
Enhanced Time-Frequency Representation and Mode Decomposition
Haijian Zhang, Guang Hua
Time-frequency representation (TFR) allowing for mode reconstruction plays a significant role in interpreting and analyzing the nonstationary signal constituted of various modes. H…
Kernel Learning for High-Resolution Time-Frequency Distribution
Lei Jiang, Haijian Zhang, Lei Yu +1
The design of high-resolution and cross-term (CT) free time-frequency distributions (TFDs) has been an open problem. Classical kernel based methods are limited by the trade-off bet…
